具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
AR头显设备是一种可佩戴在人体头部进行展示的穿戴式设备，它通过计算机技术可将虚拟的信息叠加到真实世界，使真实的环境和虚拟的物体能够实时地叠加到同一个画面中，实现两种信息的相互补充，进行视觉、听觉等信息交互，并通过头盔、眼镜等设备在用户的眼前进行画面展示，增强用户的现实感。
在相关技术中，AR头显设备一般采用眼镜形态，具体的，如图1-3所示，AR眼镜包括显示模组1和镜架3，其中，镜架3包括镜腿32，显示模组1可以设置于镜腿32上，即将显示模组1侧置，进一步的，镜架3上还安装有镜片4，且镜片4外无遮光罩，在进行画面展示时，镜片4能够将显示模组1的影像反射至人体的瞳孔内，从而使用户看到图像。
现有的AR眼镜当作为视觉交互载体，并且显示模组1侧置时，由于技术上的限制，AR眼镜结构小，且显示模组1侧置并为固定在镜腿32上，从而显示模组1无法调节自身的空间位置，因此，导致不同头围、不同瞳距的人群佩戴使用时，成像的清晰效果不同。
为能够提高AR眼镜的通用性，满足不同头围及瞳距的人群在佩带时的呈像效果，如图1和图2所示，本实施例提供了一种该AR眼镜，该AR眼镜包括上述的显示模组1和镜架3，还包括调节机构2，其中，调节机构2设置于镜架3上，调节机构2被设置成能将显示模组1显示的影像调节至设定的视野范围内。
这种结构设计，通过调节机构2对显示模组1在空间上的呈像位置进行调整，以使得显示模组1的影像能够完全进入佩戴者的视野范围内，进而满足不同头围和不同瞳距佩戴者的使用，提高了AR眼镜的通用性和功能性，增加设备的使用范围和场景。
其中，调节机构2将影像调节至设定的视野范围内的方式有多种，例如可以移动显示模组1在空间内的位置，进而改变显示模组1相对瞳孔的位置，以实现影像可以完全进入视野内。
如图1和图3所示，本实施例提供一种设计方式，具体的，调节机构2包括第一调节组件21，第一调节组件21连接于镜架3上，第一调节组件21设置成在瞳距方向X上调节影像的呈像位置，利用第一调节组件21能够改变显示模组1的影像的空间位置，进而确使影像能够进入佩戴者的视野内，通过第一调节组件21在瞳距方向X上改变影像的呈像位置，实现影像能够完全进入佩戴者的视野范围内，以满足不同头围、不同瞳距的人群佩戴。
在瞳距方向X上调节影像的呈像位置可以通过控制两个镜片4相互靠近或者远离来实现，以确保影像反射至人体的瞳孔内，从而确保用户看到图像。或者也可以在显示模组1影像的传递路径中增加反射件，以改变影像与镜片4间的入射角度，从而使用户看到图像等方式。
如图3和图4所示，在本实施例中，显示模组1通过第一调节组件21活动连接于镜腿32上，这种结构设计，将第一调节组件21设置于镜腿32上，能方便佩戴者触碰，佩戴者能够在不摘下AR眼镜的情况下，即能够实现通过第一调节组件21对影像的位置进行调节，确保影像能够完全进入佩戴者的视野内，方便佩戴者的调节。
其中，显示模组1通过第一调节组件21活动连接于镜腿32上的方式有多种，例如可以为滑动的方式。如图3和图4所示，在本实施例中，第一调节组件21包括固定架211，具体的，固定架211转动连接于镜腿32上，显示模组1安装于固定架211上，通过将固定架211转动连接于镜腿32，能够进行呈像位置的微调整，更好的实现将呈像位置调节至最佳观看区域，保障佩戴过程中的舒适感。并且，利用转动的方式，只需使显示模组1移动较小的行程，即能够实现影像在瞳距方向X上较大的位移，提高了影像在瞳距方向X上的调节范围，更好的满足不同人群的佩戴需求。
同时，将显示模组1设置于固定架211上，在实现显示模组1装配的同时，还能够对显示模组1进行保护，提高显示模组1的结构强度，并且，通过固定架211将显示模组1装配在镜腿32上，也简化了该AR眼镜的结构设计，无需较多的配件即完整了显示模组1的装配。
如图5和图6所示，在本实施例中，在进行影像呈像位置调节时，佩戴者转动固定架211以带动显示模组1同步转动，随着显示模组1的转动，显示模组1影像的光路(图5和图6中的箭头所示)在瞳距方向X上会跟随移动，即显示模组1的影像与镜片4之间的入射角度改变，从而实现在瞳距方向X上调节影像在镜片4上的呈像位置，保障完全进入佩戴者的视野范围内，以满足不同头围、不同瞳距的人群佩戴。
如图4所示，进一步的，在本实施例中，镜腿32上设置有第一装配槽321，固定架211转动连接于第一装配槽321内，通过设置第一装配槽321，在实现固定架211的装配的同时，还能够使得固定架211的至少部分隐藏在镜腿32内，简化了该AR眼镜的结构设计，无需占用镜腿32过多的空间，进而镜腿32能够布置其他部件，使得整个AR眼镜的外形结构更加简单，提高美观感。其中，显示模组1可以包括显示件11，为能够保障影像的正常传递，显示件11的部分能凸出于第一装配槽321，以避免第一装配槽321遮挡影像。
其中，显示模组1可以通过粘接、螺纹连接等多种方式连接在固定架211上。为能够更加方便显示模组1与固定架211的装配，如图7和图8所示，在本实施例中，固定架211可以包括固定本体2111，固定本体2111设置有腔体2111a，安装时，直接将显示模组1嵌入至腔体2111a内即可，装配过程快捷、简单。同时，显示模组1可拆卸地连接于腔体2111a内，即当显示模组1损坏需要维修或者更换时，还能够方便的进行拆卸。
该AR眼镜在瞳距方向X进行影像调节时，佩戴者可以直接转动固定架211进行调节，也可以通过驱动传动件的方式间接转动固定架211。如图9、图10和图11所 示，为能够使得佩戴者更加方便转动固定架211，在本实施例中，第一调节组件21还包括第一传动件212和第一驱动件213，第一驱动件213连接于镜腿32上，其中，镜腿32上还可以设置有转轴2112，固定本体2111与转轴2112转动配合，为方便结构设计，同时，实现固定架211与第一传动件212同步转动，转轴2112设置于固定本体2111上，更进一步的，第一传动件212连接于转轴2112上，第一驱动件213与第一传动件212配合，以驱使第一传动件212带动固定架211转动。
进行影像调节时，佩戴者只需通过第一驱动件213驱使第一传动件212运动，运动的第一传动件212能够驱使固定本体2111转动，进而改变影像与镜片4之间的入射角度改变，从而实现在瞳距方向X上调节影像在镜片4上的呈像位置，保障完全进入佩戴者的视野范围内，以满足不同头围、不同瞳距的人群佩戴，且调节过程简单、快捷。
其中，第一驱动件213可以是驱动电机，第一传动件212可以为传动轴，在本实施例中，为能够提高调节精度，如图11所示，第一驱动件213为蜗杆，第一传动件212为蜗轮，由于蜗杆齿是连续不断的螺旋齿，蜗杆齿和蜗轮齿是逐渐进入啮合以及逐渐退出啮合的。因此，传动过程平稳，且蜗轮蜗杆能够提供较大的减速比，因此具有调节精度高的特点，同时，还能够实现自锁，保障显示模组1位置调整后能够固定，避免由于震动、碰撞等原因导致显示模组1的影像偏移的情况发生。
如图11所示，进一步的，在本实施例中，为能够使得佩带者更加方便转动第一驱动件213，具体的，蜗杆(第一驱动件213)用于与佩戴者手指接触，并驱使自身转动的部分呈周向设置有多个第一凸棱部2131，第一凸棱部2131能够增加与佩戴者的手指之间的摩擦力，以增加转动的便捷性。
第一驱动件213和第一传动件212还可以为螺杆与齿轮轴的组合方式，或者为两个锥齿轮的组合方式，以实现固定架211的转动，在此不一一列举。
进一步的，为能够更好的满足不同头围、不同瞳距人群的配搭需求，实现把影像更加清晰的调节至佩戴者的视野范围内，还可以在人体高度方向Y上调节影像的呈像位置。其中，在人体高度方向Y上调节影像的呈像位置可以将固定架211在镜腿32上沿着人体高度方向上下滑动；或者将固定架211装配在一个旋转杆上，旋转杆铰接在镜架3上，通过在上下方向上转动旋转杆以实现在人体高度方向Y上调节影像的呈像位置。
如图12和图13所示，为能够实现在人体高度方向Y上调节影像的呈像位置，本实施例中，调节机构2还包括第二调节组件22，第二调节组件22连接于镜架3上，其中，第二调节组件22设置成在人体高度方向Y上调节影像的呈像位置。
佩戴者利用第一调节组件21在瞳距方向X上进行影像呈像位置调节后，当影像依然不能够清晰的进去瞳孔内时，佩戴者可以再利用第二调节组件22在人体高度方向Y上调节影像的呈像位置，通过在瞳距方向X和人体高度Y上对影像的呈像位置进行双维度的调节，提高了调节范围，保障影像能够清晰的进入佩戴者的瞳孔内，更好的增加设备的使用范围和场景。
如图12和图13所示，镜架3还可以包括镜框31，AR眼镜还包括鼻托5，鼻托5通过第二调节组件22活动连接于镜框31上。这种结构设计，通过第二调节组件22 来调节鼻托5的位置，从而在人体高度方向Y上移动鼻托5，以实现影像在人体高度方向Y上呈像位置的改变，其结构设计简单，且移动鼻托5的方式能够适应不同鼻梁高度的人配搭，更加满足佩带的舒适性，提高了该AR眼镜的功能性及通用性。
其中，鼻托5可以直接通过插接的方式连接在镜框31上，进行鼻托5的高度调节时，只需沿着人体高度方向将鼻托5从镜框31内抽出或者插入相应的深度即可。为能够更加方便实现鼻托5高度的调节。
如图14和图15所示，在本实施例中，第二调节组件22包括第二传动件221和第二驱动件222，第二传动件221连接于鼻托5上，且第二驱动件222与第二传动件221转动连接。佩戴者用手拨动第二驱动件222，驱动第二传动件221带动鼻托5沿着人体高度方向Y运动，以达到调节鼻托5高度，改善影响清晰度的目的。
在本实施例中，转动第二驱动件222以实现第二传动件221沿着人体高度方向运动，能将转动运动转化为直线运动，结构简单且调节方便。
如图15所示，在本实施例中，第二驱动件222与第二传动件221可以是螺纹配合，第二驱动件222为具有内螺纹的调节螺母，第二传动件221为具有外螺纹的螺杆。由于第二驱动件222(调节螺母)和第二传动件221(螺杆)均是连续不断的螺旋齿，第二驱动件222和第二传动件221的配合是逐渐进入啮合以及逐渐退出啮合的，因此，这种结构设计，具有调节精度高的特点，同时，还能够实现自锁，保障鼻托5位置调整后能够固定，避免由于震动、碰撞等原因导致显示模组1的影像偏移的情况发生。
如图15所示，进一步的，在本实施例中，为能够使得佩带者更加方便转动第二驱动件222，具体的，调节螺母(第二驱动件222)用于与佩戴者手指接触，并驱使自身转动的部分呈周向设置有多个第二凸棱部2221，第二凸棱部2221能够增加与佩戴者的手指之间的摩擦力，以增加转动的便捷性。
第二驱动件222和第二传动件221的结构形式还可以有多种，例如，第二驱动件222也可以为齿轮，第二传动件221也可以为齿条，通过齿轮齿条的方式也能够驱动鼻托5在人体高度方向Y上移动，在此不一一例举。
如图17和图18所示，其中，为使第二传动件221与第二驱动件222能够有效地接触，在本实施例中，镜框31上设置有连接槽313，第二传动件221沿连接槽313穿入并与第二驱动件222螺纹配合。
第二驱动件222可以设置于镜框31的上方或者下方，并与第二传动件221螺纹配合。如图16、图17和图18所示，在本实施例中，镜框31上设置有第二装配槽311，第二驱动件222设置于第二装配槽311内，通过第二装配槽311可以将第二驱动件222装配在镜框31内，简化了该AR眼镜的结构设计，无需占用镜框31过多的空间，同时，使得第二驱动件222与镜框31宛如一体，提高了AR眼镜外形的美观感。进一步的，为能够方便转动第二驱动件222以驱使第二传动件221上下移动，沿着人体的高度方向，第二驱动件222的两端与第二装配槽311的槽壁抵触，这种结构设计，能够实现单手操作，且保障第二驱动件222的转动过程更加稳定。
如图14、图15、图17和图18所示，进一步的，为能够使得第二传动件221能够稳定的沿着人体高度方向Y运动，防止第二传动件221跟随第二驱动件222转动，在本实施例中，第二传动件221设置有止转部2211，镜框31上设置有止转槽312， 具体的，止转部2211与止转槽312限位配合，由于止转槽312的设计，第二传动件221无法沿着自身的轴向转动，进而当转动第二驱动件222时，第二传动件221只能沿着人体高度方向Y移动，从而保障鼻托5运动过程的稳定性，防止鼻托5转动影响佩带。
如图14、图15、图17和图18所示，在本实施例中提供一种止转部2211的设计结构，具体的，在第二传动件221上设置平面区，使得第二传动件221远离鼻托5的一端形成不完整的圆柱结构，从而形成止转部2211。为保证止转部2211与止转槽312两者限位配合，将止转部2211和止转槽312的截面形状设置为相同，从而防止第二传动件221相对镜框31转动，限定第二传动件221只能够沿着人体高度方向Y移动。
除此之外，在本实施例中，还可以在第二传动远离鼻托5的一端呈周向设置有多个凸起，凸起即为止转部，其中，止转槽312的槽壁设置多个与凸起对应配合的凹槽，这种结构设计，依然能够防止第二传动件221出现转动的情况。只要保障第二传动件221远离鼻托5的一端不是完整的圆柱结构，即可满足止转部的设计需求，在此不一一列举。
综上，本实施例提供的AR眼镜能够在瞳距方向X和/或人体高度方向Y对显示模组1影像的呈像位置进行调节，通过改变影像光线的传递路径，以确保影像能够完全进入佩戴者的视野范围内，从而满足不同头围、不同瞳距的佩戴者的使用，增加该AR眼镜的使用范围和场景。
